UMBRELLA-NOTCH.

SPECIFICATION forming part Of Letters Patent N0. 710,426, dated OCtObel 7, 1902.

- Application filed May 18, 1900. Serial No. 17,177. (N0 model T0 all, whom, t may concern:

Be it known that we, WILLIAM W. CLIMBIN- soN and WILLIAM D. WINGER, citizens of the United States, residing at Honeybrook, in the county of Chester and State of Pennsylvania, have invented a new and useful Umbrella, of which the following is a specification.

This invention relates to umbrellas in general, and .more particularly to that class wherein a number of different covers are to be interchangeably connected with the stick; and it has specific reference to the formation of the notch and the means for holding the notch upon the stick.

The object of the invention is to provide a construction wherein the notch, the runner, the ribs, and the cover may be made and assembled at the factory and sold as a com plete article of commerce and having such structure that they may be applied to the stick without disasseinbling other than the upper portion of the notch to permit application of the locking-pin. As this class ot' umbrellas has heretofore been made the entire structure, with the exception of the cover, is permanently connected to the stick, and the frame of the umbrella is adapted to interchangeably receive a number of' different covers. The objection to this structure is that no two umbrella-frames have the same contour when opened, and hence while one cover may snugly lit the frame another will not.` Furthermore, in the manufacture of a number of covers of theoretically the same size there will be variations and all dimensions will not be the same. Vith our arrangement, however, the cover is accurately fitted to the frame at the factory, and hence when placed upon a stick by the purchaser it will have the same finished appearance and will be as free from wrinkles as is the fine umbrella which is completely assembled at the factory.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a view partially in elevation and partially in section and shows portions of an umbrella-stick in the form of a steel tube, said stick having the runner and the notch in place and illustrating the arrangement of the cover clamped in the notch and the location of the securing-pin. Fig. 2 is a View showing the parts of the notch detached and in perspective. Fig. 3 is a perspective View showing the-runner with the bearing-disks of the spreaderclamp separated and the clamping-nut disengaged from the threads of iheysleeveof the runner. Fig. 4 is a perspective view showing the complete article ot' manufacture, the cover, and frame.

Referring now to the drawings, 5 represents the stick of an umbrella, which is in the form of a tube, having its upper end closed by a ferrule 6 inserted therein, and provided with a handle, the invention being particularly designed for utility in a structure including a hollow or tubular stick, such as shown.

The notch of the umbrella-frame consists of a sleeve 7, having such internal diameter as to permit it to fit snugly on the stick 5, while permitting it to be moved freely, and this sleeve is screw-threaded. exteriorly and throughout its length, and with these threads is engaged a threaded collar 8, from which extends a radial flange 9, which is arc-shaped is cross-section, whereby the flange has au annular groove in its lower face, and intersecting this groove are radial slots 10. Thus the collar, and therewith the flange, may be adjusted longitudinalh1 of the sleeve as may be desired.

Cooperating with the flange 9 is the similar flange 11 of an Unthreaded collar 12, which is disposed loosely on the sleeve 7 below the collar 8, the annular groove of` the flange be-y ing in the upper face thereof to register with the groove of flange 9, and this flange 11 has radial slots 14, which are adapted to aline with their respective slots 10 of flange 9. The collar 12 is held adjacent to the collar S and with the flanges in mutual Contact or proximity, as may be required, by means of a clamping-nut 15, which is engaged with the threads of the sleeve and is adapted to impinge against the collar 12.

The ribs 16 of the umbrella have their inner ends rounded and passed through the alining slots ot the flanges and are held from withdrawal by means of cross-pins 17, which are passed through the inner ends of the ribs and lie in the grooves ofthe ilanges, thus giv- IOO ing pivotal connection between the ribs and the notch.

Formed diametrically of the sleeve 7, at a point below the upper end of the sleeve and just above the operative position of the collar 8, is a perforation, and which perforation is adapted to receive a locking-pin 20, which in practice is passed therethrough and through a diametrical perforation of the stick. In the employment of a hollow stick, as is now customary in all fine-grade umbrellas, the pin will fall down into the stick during the operation of applying or removing the piu unless great care is used when a straight pin is employed, and to prevent all chance of such occurrence the pin in the present instance is headed, the head being adapted to lie against the outer face of the collar 7.

The cover is disposed upon the sleeve 7 and lies below the perforation thereof and is held in place by the claniping-ring2l, which is substantially frusto-conical in form and is screwed down upon the upper end of sleeve 7. This collar 2l, however, must be cut away or countersunken at its lower end, as shown at 22, in order that it may pass over the head of the pin; but in thus countersinking the end of the collar a narrow lower edge 23 results, which if clamped directly upon the umbrellacover would act to cut through the cover in a short while. To prevent this, therefore, a washer 24 is first disposed upon the sleeve 7 to lie against the cover, and the collar 2l is then screwed down. In other words, the condition of the market at the present day necessitates the employment of a hollow stick, and this hollow stick necessitates the use of a headed pin. This pin has a defect which is purely incident to the use of the hollow stick-t'. e., the head-which necessitates the countersin king of the clamping-collar, and to overcome the incidental defective sharp edge the washer is employed. Thus the specific combination of the hollow stick, the sleeve, and the pin engaging perforations in the sleeve and stick have a distinct defect, which is found only in this specific combination, and When we use the countersunken collar and the washer to overcome these defects we have secured a new result-71. e., we have cured a defect which is found only in such specific combination of stick, sleeve, and pin. The washer, furthermore, cures a defect in the clamping-collar-. e., the sharp edge which is incident to the headed pin, which is in turn incident to the hollow stick-and it will thus be seen that there is a distinct correlation between the elements of the structure not only to perform their normal functions, but to modify each others defects.

The runner employed is similar to the notch in that it comprises an eXteriorly-threaded sleeve 25, having an unthreaded lower portion of lesser diameter, this Unthreaded portion 26 having the usual longitudinal slot to receive the catch upon the stick.

Collars 27 and 28 are disposed upon the sleeve 25, the upper collar having threaded engagement` and the lower collar being slidably disposed, and these vcollars have radial iianges 29 and 30, having cooperating grooves in theiradjacent faces and intersecting slots, the spreaders 3l of the frame being engaged with the slots and having cross-pins lying in the grooves to secure pivotal connection between the runner and spreaders. The lower collar is held in operative relation to the upper collar by means of a clamping-nut 32, engaged with the threads of the sleeve. This arrangement of the ribs and spreaders permits their ready application and removal. Thus it will be seen that with the present invention there is provided a complete article of manufacture which is assembled at the factory and has that structure which when placed on the market permits the ready and accurate adjustment thereof to the stick of the umbrella, so that lin each instance a complete and perfect article is produced. The frame and cover may be applied and removed by one unskilled in the art, and the parts while coperating to secure the chief functions of the structure modify each other in such manner as to eradicate the defects incident to their special forms necessitated by the peculiar conditions encountered.

What is claimed is- 1. A device of the class described comprising a notch including a threaded sleeve for engagement over a stick and having a lateral perforation to'receive an attaching-pin, ribs pivotally connected with the sleeve and located below the perforation, a clamping-collar engaged with the threads of the sleeve above the ribs and having its lower end countersunken to inclose the perforation when moved in one direction and to expose the perforation when moved in an opposite direction, and thus to cover and uncover a securing-pin engaged with the perforations and without disturbing the ribs, a washer upon the sleeve between the collar and the ribs, a shoulder upon the sleeve and extending above the ribs for impingement by the washer to exert a clamping action when moved by the clamping-collar, and a cover attached to the ribs and having its central portion disposed between the washer and the shoulder to be clamped thereby.

2. In an umbrella, the combination with a hollow stick having a transverse perforation opening therethrough, of a frame for application to the stick, said frame comprising a notch including a threaded sleeve for engagement over the stick and having a transverse perforation for alinement with the perforation of the stick, a headed pin engaged with the perforations and projecting beyond the surface of the sleeve, a shoulder upon the sleeve,ribs pivoted to the shoulder, said shoulder being located below the perforation of the sleeve, a clamping-collar engaged with the sleeve above the perforation and having its lower portion countersunken and inclosing IOO the perforation, and adapted to uncover the perforation when moved in one direction and to cover the perforation when moved in the opposite direction toward the ribs and thus to cover and uncover the ends of the securingpin without disturbing the ribs, a washer disposed upon the sleeve below the perforation therein to effect a clamping action against the shoulder when the collar is moved toward the ribs, and a cover attached to the ribs and clamped between the washer and shoulder.

3. A notch for umbrellas comprising a threaded sleeve for engagement over a stick and having a lateral perforation to receive an attaching-pin, a collar in threaded engagement with the sleeve for adjustment thereon and having a radial ange, a second collar, loosely engaged over the sleeve and having a radial flange for cooperation with the iirst flange to retain the ribs, a clamping-nut engaged with the sleeve and adapted to impinge the second collar and move it, a clampingcollar to inclose the perforated portion of the sleeve engaged with the sleeve above the first collar and a washer upon the sleeve below the perforation and adapted for movement bythe last-named clam ping-collar against the flange of the first collar, to hold a cover thereagainst, whereby the notch, with the attached frame and cover may be applied to and removed from a stick without disassembling.

'4. A notch for umbrellas comprising,Y a threaded sleeve for engagement overa stick and having a lateral perforation to receive an attaching-pin, means for attachment of ribs to the threaded sleeve, and located below the perforation, a clamping-collar engaged with the sleeve above the rib-holding means and having its lower end countersunken to inclose the perforation when moved in one direction and to expose the perforation when moved in an opposite direction, and thus to cover and uncover a securing-pin engaged with the perforation and without disturbing the rib-securing means, and a washer uponthe sleeve between the collar and the rib-holding means, for movement bythe collar against said holding means to clamp a cover thereagainst.

5. A removable notch for umbrellas comprising a sleeve, a rib-clamping member fixed upon 'the sleeve against longitudinal movement with respect thereto, a second and movable rib-clamping member upon the sleeve and having means for holding it in operative relation to the first member, said sleeve having a transverse perforation above the clamping member, a pin for engagement with the perforations and with a stick to hold the notch thereto, and a clamping-collar engaged with the sleeve and having its lower end countersunken to cover the pin and prevent its disengagement and a washer disposed upon the sleeve between the clamping-collar and the rib-clamp for movement by the collar to eX- ert a clamping action against the adjacent rib-clamping member.

In testimony that we claim the foregoing as our own we have hereto affixed our signatures in the presence of two witnesses.
